Sorry Stephen,
but as ever I was to inaccurate. That was the thing I had in my mind...
Please forgive me,
Michael

Nothing to forgive. ;-)

If you want all your slices to have the same thickness, you should add
the +1 after the multiplication.
plane {y, (Level*Slice)+1 inverse}
Otherwise, Slice=0 will be zero thickness, Slice=1 be 1 unit thick,
Slice=2 be 2 units thick...

The way I read an interpret my code is that I work from 0 to 100.
0 (Level) * Slice (thickness) = 0
(Level+1)= 0+1 = 1 * Slice = Slice thickness
Next is 1 and 2, 2 and 3, etc.
But then I've been known to have my brain convolute in upon itself like a
Gordian knot..
What you propose seems to me to actually produce the zero-thickness slices
you're warning about. But I will try it.
What makes me think my code is ok, is that when I ran some "wrong" code that
DIDN'T use the plane intersection the way I thought, I got a nice blue and green
bone with the layers stacked in the y direction. So clearly I was getting SOME
kind of actual thickness... So much unraveling to do.

Switching the placement of the inverse statement did the trick.
{whew!}
Thanks, sometimes these simple things really tie me up for far longer than they
ought to.
I need to develop a suite of "noobie tools" to help visualize these things
better.
Transparent spheres for blobs, transparent halves of planes, lines from light
locations to point at coordinates, etc.
Then I can turn on "hand-holding mode" while I create my scenes, and then turn
it off for the final render.
Oy. What would I do without you guys?
Many thanks as always!

From what I see, Alain must have misinterpreted your code. With "Slice"
being the slice thickness, you're doing it right.

Sounds familiar. Been there, done that ;-)

I'm considering building a new home there, as I expend more time
there than here... :)

Yeah, between the missing curly braces, missing end statements, confusing x, y,
and z, bouncing between different world coordinate systems, and general noob
stoopid moves like wondering why I can't see my object with thickness zero...
POV-Ray therapy group, anyone?
Anyway - one step closer to the goal.

There is a waiting list. ;-)
